Concerns have been raised that sewage is being released into the River Lagan in Belfast.
South Belfast resident Mark Walsh says he has seen sewage being released into the river from the Newtownbreda Water Treatment plant on several occasions over the past few years and is worried about how it will affect the river and the local environment.
Speaking to Belfast Live, he said: "I have seen this discharge from the river a number of times over the years into quite a clean looking area of the river, turning it brown downstream.
